I think Charles is going to be a weak king, interfering with independent institutions by sending them petty letters of complaint - he's known to do a lot of this already. (I do agree with him about much modern architecture, though.) I also don't think he'll be in the job long: he's not as healthy as his parents (says my mole in the palace).
I'll have to take your word about Edward; he used to seem a bit dim to me, but maybe he's doing the family job okay. Andrew wasn't bad as a B2B arranger, he has his mother's knack for names and jobs, but unfortunately that no longer matters.
Anne's still the only one I rate, though. She's had her own share of marital mistakes but she has the sense to shut up about them and get on with the job. She's the only one I'd invite to dinner. (Needless to say, she wouldn't come.)
